Bosch SHE43RL6UC/64 dishwasher Parts

You usually do not need a technician right away for an E24 error on your Bosch SHE43RL6UC dishwasher; it most often points to a drain path restriction you can correct by cleaning the filters and checking the drain hose and sink connection. Use the steps in the owner's manual first.

What E24 typically means

E24 is commonly tied to a draining problem: water cannot leave the tub fast enough, so the dishwasher stops and reports the error.

Quick checks we recommend first

• Turn off power to the dishwasher at the breaker before accessing internal areas.
• Remove and clean the filter area in the bottom of the tub; clear debris and re-seat the filter.
• Check the sink drain connection or garbage disposal inlet for a blockage (including a disposal knockout plug that was never removed).
• Inspect the drain hose for kinks, crushing, or a sag that traps water.
• Make sure the drain hose routing is correct and secured; avoid sharp bends.
• Run a short cycle after cleaning to confirm the unit drains normally.

When a technician (or deeper repair) makes sense

If the drain path is clear and E24 returns, the issue is often a component that needs testing or replacement.

Symptom	Most likely area	Common next step
Hums but does not drain	Drain pump or obstruction at pump	Check pump inlet for debris; replace pump if seized
Drains sometimes, then errors	Partial blockage or weak pump	Recheck hose routing; test pump performance
No drain action at all	Control, door switch, wiring, or pump	Electrical diagnosis and component testing

If you suspect the pump is not running or is jammed, the dishwasher drain pump 00642239 is the model-matched replacement part.

Why it matters

A true drain restriction can leave dirty water in the tub, cause poor cleaning, and repeatedly stop cycles. Clearing the drain path early also helps prevent unnecessary replacement of parts like the electronic control board.

Safety notes before you start

From the installation guidance for this dishwasher: avoid working on an energized circuit, and use care around sharp edges and water connections. For installation-related routing and safety details, follow the installation guide.

The most common Bosch dishwasher problem is a drain-related issue: water left in the tub because the filter area, drain path, or drain hose is restricted. On the Bosch SHE43RL6UC, the next most common complaints are leaks (often at the door seal or inlet connection) and poor cleaning from a dirty filter or blocked spray action; the owner's manual covers the routine care that prevents most of these problems.

Most common symptoms and what they usually mean

• Standing water after the cycle: clogged filter area, restricted drain hose, or a weak drain pump
• Bad odors: water not fully draining, food debris trapped in the filter area
• Leaks at the front/bottom: door seal not sealing, door not closing squarely, or overfilling
• Not filling or fills slowly: water supply issue or inlet valve problem
• Not cleaning well: filter needs cleaning, spray arms blocked, loading issues

Quick checks we recommend first (safe, no tools)

• Cancel the cycle and run a drain function; confirm you hear active draining.
• Check the sink drain/disposer connection (a blocked sink drain can back up into the dishwasher).
• Inspect the drain hose routing for kinks and make sure it has a proper high loop.
• Clean the filter area and remove any debris that can block water flow.
• Verify the hot water supply is on and the shutoff valve is fully open.

Parts that commonly solve these problems on this model

Symptom	Common fix	Part to consider
Won’t drain, water left in tub	Restore drain flow	Dishwasher drain pump 00642239
Drains slowly or leaks at hose	Replace damaged hose	Dishwasher drain hose 00668108
Won’t fill or fills slowly	Restore water inlet flow	Dishwasher water inlet valve 00622058
Leaks at the door bottom	Replace lower door seal	Dishwasher door seal, lower 00432490

Why it matters

Drain restrictions and small leaks tend to get worse over time. Keeping the filter area clean and the drain hose properly routed helps prevent odors, standing water, and repeat service issues.

Helpful DIY guidance

If you’re seeing an error code along with the problem, use our Bosch dishwasher error codes guide to match the code to the most likely cause.

Yes. The Bosch SHE43RL6UC dishwasher is a solid choice for most homes because Bosch dishwashers are built for quiet operation, efficient cleaning, and long cycle options that prioritize performance over speed. For the best results, use the cycle and loading guidance in the owner's manual.

What “good” usually means for this model

A dishwasher is “good” when it cleans consistently, runs reliably, and fits your kitchen and routine. With the SHE43RL6UC, we typically see customers value:

• Quiet operation compared to many older dishwashers
• Strong wash performance when filters and spray paths are kept clear
• Multiple cycle options (normal, heavy, rinse, etc., depending on configuration)
• Good long-term serviceability with replaceable parts like pumps, valves, and seals
• Efficient water use (performance depends heavily on loading and detergent)

Quick checks to decide if it is right for you

Use this checklist to match the dishwasher to your expectations:

• If you want faster cycles, confirm cycle times and options in the owner's manual
• If you have hard water, plan on regular filter cleaning and proper detergent use
• If you run overnight, prioritize quietness and reliable draining
• If you cook with heavy soils, choose heavier cycles and avoid overloading
• If you want DIY-friendly repairs, confirm common parts availability

Common “good dishwasher” issues and the parts that often fix them

If performance drops, it is usually maintenance or a single failed component.

Symptom	Common cause	Example part for this model
Not filling	Water supply issue or failed inlet valve	Dishwasher water inlet valve 00622058
Not draining	Clog, hose routing, or failed drain pump	Dishwasher drain pump 00642239
Poor cleaning	Filter restriction or weak circulation	Dishwasher circulation pump 00442548
Leaking at the bottom of the door	Worn lower door seal	Dishwasher door seal, lower 00432490

Why it matters

A “good” dishwasher is mostly about consistent wash action and correct installation. For example, Bosch installation guidance calls for routing the drain hose with a high loop (at least 20 inches off the cabinet floor) to help prevent draining problems and backflow; that directly affects day-to-day reliability. Review the installation requirements in the installation guide.

To force-drain a Bosch dishwasher like model SHE43RL6UC, we cancel the current cycle: press and hold Start (or Reset/Cancel) for about 3 to 5 seconds until the display changes, then let the unit run the drain-out. If it still will not drain, a clog or drain-path issue is stopping the pump.

Quick steps to force a drain

• Press and hold Start (or Reset/Cancel) for 3 to 5 seconds.
• Close the door fully and wait; the dishwasher should begin draining.
• If the control panel is unresponsive, turn power off at the breaker for 1 minute, then retry.
• If water remains, remove the lower rack and check the sump area for debris.
• Confirm the drain hose routing is correct (see the 20-inch high loop requirement in the installation guide).

What to check if it will not drain

Most no-drain problems come from a blocked filter/sump, a kinked hose, or a failed drain pump.

• Filter and sump: Clear food, glass, labels, and twist ties.
• Drain hose: Look for kinks, crushing, or a blocked air gap (if installed).
• High loop: The drain hose must rise to at least 20 inches above the cabinet floor or draining can be poor.
• Drain pump: If the pump hums but does not move water, the impeller may be jammed or the pump may be failing.
• Error indication: If an error code appears, use Bosch dishwasher error codes to match the code to the most likely drain-related cause.

Parts that commonly fix draining issues

Symptom	Most likely area	Example part for SHE43RL6UC
Hums but no water movement	Drain pump/impeller	Dishwasher drain pump 00642239
Slow drain or backs up	Drain hose routing/clog	Dishwasher drain hose 00668108
Won’t fill and then won’t drain correctly	Water level/fill issues	Dishwasher water inlet valve 00622058

Why it matters

Standing water can cause odors, redeposit soil on dishes, and trigger Bosch drain-related faults. Correct drain hose height and a clear filter path help the drain pump move water out quickly and consistently.
